C# script to rotate GameObject to mouse cursor.

difference.Normalize();
float rotation_z = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, rotation_z + offset);

Unity 2D C# Rotate GameObject To Mouse Cursor
Any way to slerp to the position?
Change this: transform.rotation = Quaternion.Euler(0f, 0f, rotation_z + offset);
to this: transform.rotation = Quaternion.Slerp(from.rotation, rotation_z + offset, Time.time * speed);
and add public float speed at top of the script
I have not tested it, but I think it should work 😉
hi thanks for your very good codes.. slerp need Quaternion but rotation_z is a float and Causing an error
could we Create a variable of type “Quaternion ” and entered numbers… Az rotation_z in it? pls type hire that codes tnx
my english is bad 🙂 also my programing : ))
this is working 🙂 —enjoy
public class test3 : MonoBehaviour {
public Transform from // drag your Obj to this in unity Panel
public float speed = 1.5F;
void Start () {}
void Update () {
Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector2 direction = mousePos – transform.position;
float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
Quaternion myrotation = Quaternion.AngleAxis(angle, Vector3.forward);
transform.rotation = Quaternion.Lerp(transform.rotation, myrotation, speed*10 * Time.deltaTime);
if (Vector2.Distance(from.position, mousePos) > 0.9f {
transform.position = Vector2.MoveTowards(from.position, mousePos, speed * 2 * Time.deltaTime); // for Move Object : ))
}
}}
my rotation is delayed by 90 degrees, do you have any idea why?
Your sprite is probably rotated, change offset, as shown in the second video 🙂
How can we rotate the game object to right and left with using keys like “a” and “d”? And then maybe go forward with the key “w”.
this is work 100% – change “yourNameScript” to yourNameScript 🙂
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class yourNameScript : MonoBehaviour {
public Transform from; // drag your Obj to this in unity Panel
public float speed = 1.5F;
void Start() { }
void Update(){
Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector2 direction = mousePos – transform.position;
float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
Quaternion myrotation = Quaternion.AngleAxis(angle, Vector3.forward);
transform.rotation = Quaternion.Lerp(transform.rotation, myrotation, speed * 10 * Time.deltaTime);
if (Vector2.Distance(from.position, mousePos) > 0.9f ){
transform.position = Vector2.MoveTowards(from.position, mousePos, speed * 2 * Time.deltaTime); // for Move Object : ))
}}}

Edit yourself
I tried this but on a 3d Object, and it never stopped moving anyone know why?
Is there a way to offset the rotation origin? right now this script rotates from the game object’s origin so it only rotates on top of that, with no distance in between; I am trying to rotate a child object around my character, so i’d like some distance between the two, so my rotating is some distance/radius away from its parent, so both are visible, think enter the gungeon.
any help is appreciated thanks,

It is, create new empty GameObject, add this script to it, and inside it place your object(without script) and move it a bit relative to parent object. Hope it helps 🙂
guess what, it DID help !! works perfectly now, thanks for the speedy reply, you are awesome !!

Glad to hear that, have fun with it 😉
How to implement this concept unity 3D
Thank you, Ive been trying for the last 3 hours to get it to work and tried bunch of codes.
